An adult man and woman suddenly lose consciousness and wake up locked inside a bare room. Every door is sealed, and the only objects are a bed and an envelope reading, “You cannot leave this room without having sex.” With no food, toilet, or way to contact the outside world, they must decide whether to have sex to escape. Multiple fixed cameras capture their despair, inner conflict, desperate struggles, and the final choice they make, all from the captor’s controlling point of view.
